Hanging cabinets

So I'm completely new to the forums but have been eyeballing teardrops for years. I bought my first one and it gets delivered Sunday. It is brand spanking new. A 4x8 "square" "doghouse" design, very similar to the runaway navigator. It has a galley in the back with a mini fridge, stove and shelves. The inside is nothing but a shell with a fantastic fan in the roof. Now I'm looking to hang bathroom cabinets on the wall that separates the interior from the galley. It is 3/4" thick plywood. My question is how much weight can it support? I found these sweet ikea cabinets that I think would look great and 3 of them would fit perfectly across the interior, but weight 25lbs a piece so that's 75lbs. Can it support that, and if not any suggestions? Ideally I'd like one cabinet on each side with shelves in the middle holding a tv/computer. Anyways any help and any ideas are geary appreciated.
